Differences in hairdressing head model training systems

‌Japanese system‌: emphasizes tool placement (scissors and head model at 45 degrees), number of actions (single haircut action repeated 5000 times);

‌European and American system‌: focuses on creative divergence (score of coordination between head model facial contour and hairstyle);

‌Assessment standards‌: Japanese JEA certification requires BOB hairstyle to be completed within 6mm error, and American AACS requires 10mm.
